Fig. 2 is the detonation configuration schematic diagram held down assembly.

Embodiment

See figures.1.and.2 and a kind of jointing clamp of electric meter of the utility model is described further.

A kind of jointing clamp of electric meter, comprise C clamp seat 1, be arranged on the clamp block 2 and latch segment 3 that cooperatively interact in C clamp seat 1, fastening bolt 4, nut 5, main line chamber 6 is formed between the inwall of C clamp seat 1 side and clamp block 2, latch segment 3 is provided with service wire lockhole 7, the inwall of C clamp seat 1 opposite side is provided with watt-hour meter service wire and passes and be fixed on the service wire through hole 8 in service wire lockhole 7, C clamp seat 1 is provided with limiting section 9 near latch segment 3 side, side, latch segment 3 relative limit portion 9 is provided with Access Division 10, this Access Division 10 can be press-fitted in down on limiting section 9 and latch segment 3 is conflicted with C clamp seat 1 sidewall and be connected, clamp block 2 be provided with groove 21 near one end of C clamp seat 1 sidewall and be combined with adjustable main line chamber 6 size hold down assembly 11.

This jointing clamp of electric meter is by being provided with limiting section 9 at C clamp seat 1 near latch segment 3 side and side, latch segment 3 relative limit portion 9 is provided with the setting with the Access Division 10 of limiting section 9 adaptation, location is realized to latch segment 3, no matter how before clamping ammeter service wire, it is the state how upwards to have supplied, press down after locking due to the interaction between limiting section 9 and Access Division 10, latch segment 3 can be conflicted all the time and be connected C clamp seat 1 sidewall, reduce the too small impact on latch segment 3 grip size of main traverse line, remain high grip, and then raising stability, clamp block 2 near be provided with C clamp seat 1 side be provided with groove 21 and be combined with hold down assembly 11 setting, even if main traverse line is too small like this, also can regulate hold down assembly 11 overhang reach and regulate main line chamber 6 size to guarantee main traverse line clamping stable to control a suitable size, C clamp seat 1 is often increased to guarantee the enough large of main line chamber 6 by above-mentioned two-part setting, adapt to the size of the main traverse line of different size ammeter box, and then improve adaptability and facilitate clamping.

Limiting section 9 comprises the stopper slot 91 and protruding 92 that are disposed adjacent, the cross section of protruding 92 is arc-shaped, limiting section 9 is made up of the stopper slot 91 be disposed adjacent and protruding 92 and guarantees its spacing to add strong stability further to latch segment 3, the cross section of protruding 92 be arc-shaped be arranged so that latch segment 3 upper confession and pressing down in process can not be restricted or restraint very little and then easy to setup.
